So here's an update to my Anvil experimentation (original post about a page and a half back):
I got the Anvil MM "Dandelion Drops" a few days ago. After a wash and dry (I never wear unwashed clothes, and I'm too lazy and impatient to hang-dry), I wore it all day yesterday. It definitely fits like a guy's shirt should - longer torso, straight cut, longer sleeves. Frankly, aside from the sleeve length, which doesn't bother me a bit, it fits just like the AA WXL shirts did, and maybe hangs just a smidge longer. The fabric is a little heavier and rougher, but not so much so that I wouldn't wear it.
All told, if I were to buy another Woot shirt, I'd buy a MM. I do wish that Woot had switched to a ladies blank that was more flattering to all, and was sized to fit more women, beanpole and curvy. I was in the target group for the change (would have loved a W2XL AA), but I've been forced to buy a men's shirt to avoid looking like a hot, sloppy mess. I also wish that I had figured out the sizing issue before "Almost Free" was reckoned. As it stands, I don't see myself wearing the Anvil AM fishy without a layer on top, because the waistline is so very unflattering.
So if you're like me, and you were hoping for a shirt that fit like an AA WXL with a little more breathing room, I suggest the Anvil MM (all other sourcing/manufacturing issues aside).
